Sup Oppo, what do you keep on your keys?

What's On Your Keys?S

All I have is my CTY Lancaster 2011 and 2012 lanyards, and a small flashlight that my dad gave to me because my car is way out by the barn. I don't really like the flashlight, as its bulky. (Car is a 2007 silver Volvo xc-70, official car of northeastern prep school kids who's parents aren't BMW giving morons. Theres at least 5 at my school)

What do you keep on your keys? Whats your opinion on lanyards? Separate key rings? Souvenirs?
